One thing that live apps on the lockscreen are perfect for is changing the wallpaper. Many apps have already come out with this feature, including our favorite Reddit app Baconit. The newest app to do this is called Paper Shuffle, and it might be the one you have been waiting for.

Paper Shuffle is dead simple. All you do is choose a few photos saved on your phone, select the frequency for rotating the images, and you’re done. The app will do the rest. It can change your lockscreen image every hour, day, every other day, or every week. The full version of the app is $.99, but there is a free trial that has a three image limit.

A lot of users have been asking for an app that does exactly what Paper Shuffle does. It was inevitable that an app like this would come, and it looks like this developer won the race.
